High weather resistance elastic hardener FEICURE GB905A-85

Ⅰ Chemical formula and molecular weight
● Chemical Name: Elastic Curing Agent GB905A-85(High Weathering Resistance)
Ⅱ Properties and application
●Self-developed elastic polyurea curing agent, GB905A-85 can be the material for two-component polyurea/polyurethane after reaction with NH or OH-contain resin, and it is with excellent performance such as quick cure, better elasticity, mechanical strength, longer QUVa, as well as anti-acid/alkali/salt.
Application 1. After reaction with self-developed PA resin D2925 or F420, this cure agent can be made into a top coat with high-elastic, high-abrasion, longer weather-resistance performance. 2. Used as topcoat for waterproof/abrasion, projects like high-speed rail or architecture 3. Replaced with FC and overwhelm it with higher-elasticity and better anti-abrasion performance 4. All kinds of elastic material
● Main Feature 1.High strength 2.High elasticity 3.High weathering resistance
