Coated silica gel

Coated silica gel is a kind of new environmental protection material, has now been widely used in People's Daily necessities. It is a kind of liquid material, is the most widely distributed in nature silica powder as raw material, through reaction with oxygen, sulfur, nitrogen and organic matter, organic matter and silicon atoms connected and generate compounds. Coating, it is for the sake of anti-corrosion, insulation, decoration and other purposes, in the form of liquid or powder in fabric, paper, metal foil or objects such as plastic thin layer coated on the surface cover.

use

Coated silica is widely used in pure cotton cloth, twill, nylon fabric, linen, wool cloth, silk cloth, anti-slip cloth, waterproof fabric, packing cloth, high temperature resistant, good low temperature resistance, insulation cloth, anti-corrosion, wild with senior senior zhang peng cloth, umbrella cloth, ageing resistance fabric, and so on the fabric coating processing and antiskid purposes.

Characteristics of coated silica gel products

, low shrinkage rate, not emit low molecular crosslinking process, so the volume, shrinkage rate is less than 0.1%

• antiskid performance is wonderful; No pollution; Low hardness. Firm adhesive of graft.

, wear-resisting, washable, resistant to high temperature; Three-dimensional level is high, quality excellent, for easy to operate, can be widely used for ornamental design belt, ribbon, non-slip belt, woven label brand products special sign silicone (silicone fabric coating), prevent slippery floriation tablecloth, medical garter.

, food grade, avirulent insipidity, through the FDA food grade certification

, high transparency, high tensile strength, tear strength, good bonding effect

Coating adhesive use method and matters needing attention

, A, B two weight 1:1 mixing, after vacuum deaeration to operation.

, and used while operating separate containers, condensation type silicone with unused room temperature silicone tool operation the silica gel.

, can't contact with plasma compounds containing N, P, S and acetylene and vinyl compounds, lest make platinum catalyst poisoning, not curing, especially PVC containing Pb (lead), can make the catalyst poisoning some organic pigments can also lead to cure slow or no cure.

Coating adhesive typical curing conditions

Moderate viscosity, high temperature curing, high transparency, good adhesion, heat resistance, water resistance, permeability is good.
