Application

1.Vinyltriisopropoxysilane is a vinyl silane monomer used for cross-linking vinyl and acrylic emulsions for use in OEM products and architectural coatings， which are easily copolymerized into the backbone of vinyl and acrylic emulsions, The formulation of the recommended catalyst provides a hard and highly cross-linked coating after curing. The unique structure of the silane makes it very stable in aqueous systems and does not react or cross-link before the coating is condensed. The aqueous coating formulation containing the product remains stable and effective after one year of aging.

2.Copolymerization of KH-1706 acrylic and vinyl emulsions offers new options for the preparation of formaldehyde-free and one-component water-based coatings.

This kind of emulsion can be used in:

1. Kitchen cabinets, industrial and senior furniture, wood coatings

2. Furniture, fixtures, machinery and equipment, metal coatings

3. High-performance architectural coatings

4. Plastic paint main advantages: Adding 5%-10% KH-1706 Silane to the main chain of the emulsion resin can significantly improve the performance of the coating after curing:

1) solvent resistance, water resistance, scratch resistance

2）the pigment adhesion and scrub resistance

3）wet and dry adhesion

4）the coating hardness, tensile strength

4. Application effect

Add 0.2 to 15% of the product to the main chain of the emulsion resin can significantly improve the performance of the coating after curing.

★ Solvent resistance ,water resistance

★ anti-scratch

★ wet and dry adhesion

★ the hardness of the coating

★ Tensile strength.

5.Package and storage

Before using this product, you should carefully read the product's latest product safety technical information and toxicity data and the correct storage and use of the product information.

After the container is opened, it should be sealed to prevent water vapor from entering the hydrolysis. Usually the valid time is one year.

The initial introduction of our Divinyltetramethyldisiloxane (VMM) CAS No. 2627-95-4 to the market has been a great success due to our proven technological development. Integrity is the leading idea of our company, we take the specialty as the survival way of the enterpris and take the enthusiasm service as the development road of the enterprise.
