Development Of Spray Polyurea Curing Crosslinking Agent DETDA (E100) Elastomer Technology

Development Of Spray Polyurea Curing Crosslinking Agent DETDA (E100) Elastomer Technology

Spray Polyurea Elastomer (Spray Polyurea Elastomer, Hereinafter Referred To As SPUA) Technology Abroad Over The Past Decade, Following The High-Solids Coatings, Waterborne Coatings, Light-Cured Coatings, Powder Coatings And Other Low (No) Pollution After Coating Technology, To Adapt To Environmental Protection Demand And Developed A New Type Of Solvent-Free, Pollution-Free Green Construction Techniques. This Technology Since 1999 Invested In Our Business Applications, Has Been In The Field Of Steel Corrosion, Building Waterproofing, Film And Television Props, Etc., It Has Been Widely Used.

Our Spray Elastomer Technology Has Undergone More Twists And Turns In The Development Process: In The 1990s, Shanxi Institute Of Chemical Engineering Zhang Quan Sheng Deng Who Use Bayer'S Conduct G31 Sprayer Spray Polyurethane Elastomer Technology Research And Development. However, Because Of Technology And Market, Has Not Been Large-Scale Commercial Applications. Series Of Products Related To Corrosion, Waterproof, Anti-Skid Many Areas, Decorative, Sets, Props, Wear-Resistant, Acid And Alkali, Anti-Aging, Impact Resistance, Etc., And Have Published Numerous Articles, Applied For A Patent. Applications Involving Tunnel Waterproofing, Corrosion And Other Sluice. 2001 Hunan Xiangjiang Paint Group Co., Ltd., Who Carried Out 贺光辉 Spray Polyurea Elastomer Technology Developed In Terms Of Pickup Trucks Lining Wear, At The Same Time, The United States SPI, United Coatings, Mountain Polyurethane Korean Companies, Capital Chemistry Companies And Other Enterprises, Also Have Their Products Sold In The Domestic Market.
,
With The Development Of Polyurea Spray Polyurea Elastomer Technology, Which Is Defined More And More Clear. United States, "Polyurea Development Association" (Polyurea Develop-Ment Association, Referred PDA) For Spray Polyurethane, Polyurethane (Urea), Polyurea Is Defined As: Spray Polyurethane: By Isocyanate Component (Referred To As A Component) With The Resin Component (Referred To As R Component) An Elastomeric Substance Generated By The Reaction. Isocyanates Can Be Both Aromatic, It May Also Be Aliphatic. A Component Which May Be A Monomer, Polymer, Derivative Isocyanate Prepolymers And Semi-Prepolymers. Prepolymers And Semi-Prepolymers From The End Of The Polyol With An Isocyanate Reaction. Wherein R Is A Terminal Hydroxyl Component Must Resin (Eg: Diol, Triol, Polyhydric Polymer Polyols, Etc.) And An Aromatic Or Aliphatic Hydroxyl Side Chain Extender Composition, The Terminal Hydroxyl Resin Must Contain For Increasing The Catalyst Activity.

Spray Polyurethane (Urea), Also Known As Hybrid, Which Is Composed Of The Isocyanate Component (Referred To As A Component) With The Resin Component (Referred To As R Component) An Elastomer Material Generated By The Reaction. Isocyanates Can Be Both Aromatic, It May Also Be Aliphatic. A Component Which May Be A Monomer, Polymer, Derivative Isocyanate Prepolymers And Semi-Prepolymers. Prepolymers And Semi-Prepolymers From The Terminal Amino Group Or Terminal Hydroxyl Compound With An Isocyanate Reaction. Wherein The R Component May Be Either A Terminal Hydroxyl Resin (Or Chain Extenders), The Resin May Be A Terminal Amino Group (Or Chain Extenders). In The R Component, It May Be Contained For Increasing The Catalyst Activity.

Spray Polyurea: By Isocyanate Component (Referred To As A Component) With An Amino Compound Component (The R Component) Produced By The Reaction Of An Elastomeric Material. Isocyanates Can Be Both Aromatic, It May Also Be Aliphatic. A Component Which May Be A Monomer, Polymer, Derivative Isocyanate Prepolymers And Semi-Prepolymers. Prepolymers And Semi-Prepolymers From The Terminal Amino Group Or Terminal Hydroxyl Compound With An Isocyanate Reaction. Wherein R Component Must End By An End Amino Resins And Amino Chain Extender Composition, Amino Resin In The End, May Not Contain Any Hydroxyl Component And Catalyst, But May Contain A Pigment Dispersing Additives Facilitate.

Spray Elastomer Originated In The 1970s, The Early Varieties Are Sprayed Polyurethane Elastomer (Referred To As SPU). Since Its Construction, The System Is Easy To Ambient Moisture, It Reacts With Moisture To Produce Carbon Dioxide, Generated Foam Elastomer (Foamy Elastomer), Resulting In An Unstable Mechanical Properties. Therefore, People Will Soon Think Of Terminal Amino Compound Is Introduced In The Resin Component, Namely Spray Polyurethane (Urea) Elastomer (SPU [A]).

Development Of Spray Polyurea Curing Crosslinking Agent DETDA (E100) Elastomer Technology, DETDA Chemical Name Diethyltoluenediamine, Equivalent To Ethancure 100 And Lonza DETDA 80. Is A Very Effective Polyurethane Elastomer Chain Extender, Especially For RIM (Reaction Injection Molding) And SPUA (Spray Polyurea Elastomer); A Polyurethane Elastomer And Aromatic Diamine Curing Agent Of Epoxy Resin With For Casting, Coating, RIM And Adhesives, Also Polyurethane Polyurea Elastomer And A Chain Extender, But Also Can Be Used As Polyurethane And Epoxy Curing Agents, Epoxy Oxygen Agents, Industrial Oils And Lubricants.

Urea Coating Characteristics
Polyurea Coatings Usually Have The Following Characteristics:
(1) No Catalyst, Fast Curing, Can Be In Any Surface, Inclined And Vertical Surfaces Spray Forming, Not Sagging, 5 Seconds Gel, 10 Minutes To Reach On Foot Strength.
(2) Water, Moisture Insensitive, Unaffected By Temperature And Humidity During The Construction.
(3) Two-Component, 100% Solids, Environmentally-Friendly, Can Be 1: 1 Ratio By Volume Spraying And Pouring, Once Construction Reaches Required Thickness, To Overcome The Shortcomings Of The Conventional Multi-Layer Construction.
(4) Excellent Physical Properties, Such As Tensile Strength, Flexibility, Abrasion Resistance And The Like.
(5) Has Good Thermal Stability, Long-Term Use At 150 ℃, Can Withstand Short-Term Thermal Shock Of 350 ℃.
(6) Can Be Added To A Variety Of Pigments And Fillers, Made Of Different Colors Of Products.
(7) Formulation System Adjustable Feel From Soft Rubber (Shore A30) To A Hard Elastomer (Shore D65).
(8) Can Be Introduced Into The Chopped Glass Fiber Reinforced Materials.
(9) Complete Spraying, Pouring Equipment, Construction Convenient, High Efficiency.
(10) The Device Is Equipped With A Variety Of Switching Modes, Either Spraying, Can Also Be Cast. In Recent Years, Spray Molding (Or Injection Molding) Has Become An Important Elastomer Molding Method. Polyurethane (Urea) Elastomer Solvent-Free Spray Molding Is The Use Of Pressure Polyurethane (Urea) Material Conveyed By The Metering Pump To The Gun, After Rapid Mixing, Spraying The Surface To Be Molded. Spraying Equipment, Small Size, Light Weight, Easy Handling, Flexible Operation, Easy Construction, High Efficiency, Especially For Construction Of Wear, Corrosion Protection Layer Lining The Large Range Of Pipeline Construction And Container. Molded Elastomer Coating Without Preheating And Heat Curing.
