Aqueous blocked isocyanate 1675

  1
  Principal component: Type: HDI , Solid content /%: 75
NCO/%：11  Viscosity / MPa s：2000
Unsealing temperature: 135 ℃
2
product characteristics: the curing agent can coexist with waterborne resin (waterborne polyurethane, waterborne acrylate, fluorine emulsion, silicone emulsion, etc
) at room temperature for a long time
When heat treatment, the curing agent releases the isocyanate (-nco) group to react with the active groups such as hydroxyl, carboxyl and amino groups on the molecular chain of the waterborne resin to form cross-linked structure, which can significantly improve the properties of the waterborne resin

Scope of application:
①  As the internal crosslinking agent of one component heat curing waterborne coatings, the water resistance, chemical resistance, wear resistance, adhesion and mechanical properties of waterborne resin paint film are significantly improved by curing and crosslinking

②  As an bridging agent for organic fluorine or silicone emulsion, the organic fluorine or silicone is fixed onto the surface of cotton fiber or polyester fiber to increase &ldquo
Three prevention & rdquo; The number of washable times of the fabric

③  As the internal crosslinking agent of textile coating and printing adhesive, it can improve the adhesion, washing resistance and wear resistance

④  As an internal crosslinking agent for one component metal baking paint, it can replace amino resin, improve brittleness, no formaldehyde release, and has excellent yellowing resistance
