Detailed introduction of "PE bonding dimer acid polyester polyol BY3022"
PE bonding dimer acid polyester polyol BY3022 Basic introduction
BY3022 adopts a new synthesis process and uses a special water-resistant monomer dimer acid, which makes the polyester polyol have excellent water resistance, corrosion resistance, and UV resistance. BY3001 also has excellent adhesion, suitable for Production of PU elastomers, PU adhesives, coatings, water-based PUD, UV polyurethane paints, etc.
PE bonding dimer acid polyester polyol BY3022 Characteristics
Excellent water resistance. The performance is comparable to that of polycarbonate polyol, and better than that of polytetrahydrofuran ether PTMG and polycaprolactone polyol PCL;
Excellent acid and alkali corrosion resistance, heat resistance and solvent resistance;
Outstanding anti-ultraviolet light performance, obvious in terms of UV resistance performance Polytetrahydrofuran ether polyol;
Excellent antistatic properties, oxidation resistance, halogen resistance, good weather resistance;
Good adhesion and bonding properties to non-polar substrates (such as PE, etc.) and substrates with ground surface energy;
Good leveling and substrate wetting;
Good impact resistance and flexibility, good elasticity, bending resistance and stable hardness at low temperature PE bonding dimer acid polyester polyol BY3022 Technical parameters Appearance Waxy solid Molecular weight 2000 Hydroxyl value 50-60 mgKOH/g Acid value ＜0.8 mgKOH/g Moisture ＜0.1% Softening point 37-45 Chroma ＜4
PE bonding dimer acid polyester polyol BY3022 Instructions for use 【main application】
●Polyurethane elastomer TPU. Synthesize high-performance polyurethane elastomer with weather resistance, light resistance, UV resistance and hydrolysis resistance.
●UV oligomer. Synthesize UV oligomers with high resistance to hydrolysis, weathering, light, and chemicals while reducing their shrinkage properties.
●The field of foamed polyurethane. Polyurethane foam synthesized from dimer acid polyol has good external performance and durability.
●Polyurethane sealant. For moisture-cured polyurethane sealants, it can improve weather resistance, light resistance, and UV resistance, especially for external use
The field of polyurethane sealants; at the same time, it has good bonding properties, for untreated non-polar substrates, such as difficult-to-bond PE substrates,
Still has good bonding properties. ●Polyurethane leather finishing agent. It can produce polyurethane emulsion with excellent hydrolysis resistance and good heat resistance stability.
●PU adhesive for ink\coating\adhesive; cable sheath, hose, barrier film and sealant, etc. PE Bonding Dimer Acid Polyester Polyol BY3022 Purchasing Instructions This product is a non-dangerous product. It is transported in a conventional way. It is recommended to store it in a sealed place at 5-35°C and avoid light. The shelf life is 1 year.
Can still be used after passing the test.
