Product Overview
2031 is a high concentration of amino functional group organometallic adhesion promoter, adsorbed on a high specific surface area
The precipitated silica is a dry and free-flowing solid powder, which is mixed by physical crushing (Banbury,
Henschel, etc.) to release the adhesion promoter of amino functional groups, relative to 2031, introduced into coatings, rubber and other systems
The carrier solvent content should be reduced by 65%.
Physical properties
Form: Flowable solid
color: White
Comprehensive performance
Coatings: recommended for phenolic, polyester, acrylic, and polyurethane coatings, which are difficult to handle when adding liquids
On the metal (CRS, aluminum, brass) substrate, it can improve the resistance to salt spray, anti-explosion bubbles and reduce the creep after the grid.
Adhesives: recommended for epoxy, polyurethane, and rubber adhesives, used for lifting and metal, plastic and
Adhesion on elastomers. Improve the T-peel strength and improve the ability to resist humidity, heat and corrosive environment.
Application, recommended dosage and usage
Coating: 0.5-1.5% recommended addition, high-shear mixing is recommended (Henschel, etc.), not more than
The recommended amount
Binder: 0.5-1%, add resin and mix well.
Plastic: 0.5-1% (relative to the amount of 100% filler), can be directly added together with resin, filler and other additives
Out of the machine, it is recommended for pigments and fillers with high specific surface area, such as fumed silica, carbon black, phthalocyanine series and similar products.
The amount is 1-2% (relative to the amount of 100% filler).
Rubber: 0.7-1.4%, directly added and mixed, and mixed with Banbury mixing equipment.
