Detailed introduction of "OPP bonding dimer acid polyester polyol BY3026"
OPP bonding dimer acid polyester polyol BY3026 Basic introduction BY3026 is a low viscosity flowable dimer acid modified polyol, the polyester diol has excellent high and low temperature resistance, flex resistance, substrate wetting, improved adhesion, water resistance, hydrolysis resistance And UV resistance, suitable for the production of polyurethane elastomers, adhesives, coatings and other products.BY3026 has the properties that polycaprolactone polyol and polycarbonate polyol are difficult to achieve in many application fields, especially in the adhesion of plastic and metal substrates, adding 10-30% in the formula can achieve very high performance. Good performance improvement. OPP bonding dimer acid polyester polyol BY3026 Characteristics Good adhesion to hard-to-adhere substrates, such as PP, PE, PET, PVC, PS, aluminum foil, metal oxides, plastics, etc.
Excellent water resistance and excellent hydrolysis resistance;
Excellent oxidation resistance, good acid and alkali resistance, heat resistance and weather resistance;
Good flexibility and tensile properties, can improve the folding resistance of polymers, and also have good performance at low temperature;
Low viscosity, synthetic polyurethane can be used with reduced or no solvent. OPP bonding dimer acid polyester polyol BY3026 Technical parameters Appearance light yellow flowable liquid
Molecular weight about 2500g/mol
Hydroxyl Value 37-43 mgKOH/g
Acid value ＜1.0 mgKOH/g OPP Bonding Dimer Acid Polyester Polyol BY3026 Instructions for Use 1. High water resistance PUD, TPU, CPU.
2. UV oligomer. Improve hydrolysis resistance, weather resistance, light resistance, and reduce shrinkage of light-cured products.
3. Polyurethane sealant. For moisture-cured polyurethane sealants, it can improve weather resistance, light resistance and UV resistance, especially suitable for exterior
Used in the area of polyurethane sealant.
4. Polyurethane resins for inks, coatings, adhesives and leather finishing agents. Can produce excellent hydrolysis resistance and bending resistance
