1) polyvinyl alcohol. 5 formula for polyvinyl alcohol, alcohol, 35, washing powder, 1; Preparation technology for some of the polyvinyl alcohol solution (heated 60-70 degrees), and then add a little water, stir, then add alcohol and dissolving detergent, finish blending to white precipitate dissolves. Compatible with unsaturated polyester and epoxy resin products for release.

2) Pam: formulation and the preparation technology and application (1).

3) organic solvent solution of cellulose acetate, polystyrene can also release agents.

4) cellulose acetate, polystyrene organic solvent solution release agent can also be used.

5) water based release agent containing masking agent. Recipe: 2.7 microcrystalline wax, polysiloxane 2 heavy petrolatum 7.88, fungicide

0.1, adducts of fatty alcohols 1.5, Nonylphenol EO adducts 0.4, 0.32 fatty alcohol polyglycol ether mixtures, water 84.73. First one-second of water heated to 95 degrees, stirring added each of these components, and joining the emulsifier. Appropriate release agents for polyurethane products.

6) durability of release agents. 200ml mixed solvents (xylene: Ethylbenzene: ethane: toluene = 82:16:5:1) to include Me3SiCl 1.6 Si (OEt) 4 1.0, water 19.2mol, at 25 degrees Celsius-mixing 1h, get the silicone resin solution. This solution 15, dimethyl siloxane (viscosity 200Pa.s) 66 19 mixed mixed solvents. To methylene chloride into 4%~ 10% solution. Suitable for release of polyurethane foam products, 1 film can be reused hundreds of times.

7) multilayer composite release agents. Bottom for short chain tetrafluoroethylene Telomeres; 2nd floor is for polyethylene; 3rd floor is for polyvinyl alcohol.

Long-term use of underlying damage should be updated in a timely manner; 2nd, 3 layer needs to be updated often. Suitable for ultra-microporous polyurethane release.
