Dabco 8154 is an acid-blocked tertiary amine catalyst, which is mainly used to promote the reaction of urethane (polyol-isocyanate) and has the effect of delaying the initiation of the reaction;
Dabco 8154 is mainly used for polyurethane molded foam, prolonging milking time, improving fluidity and improving processing efficiency of foam.
Dabco 8154 catalyst is a blocked tertiary amine polyurethane catalyst, which mainly promotes the reaction of polyurethane foaming urethane (polyol-isocyanate), while providing delayed catalytic effect in soft and rigid polyurethane foaming.
Typical physical properties:
Appearance Amber transparent liquid
Specific gravity 1.04
Viscosity@25℃ mPa.s 160
Water soluble at 25℃, completely dissolved
Flash point, ℃ 110
Polyurethane delays gel catalysis and provides excellent fluidity
Improve the curing time of polyurethane foam without extending the demoulding time
Corrosion is lower than other polyurethane delayed catalysts
Dabco 8154 catalyst is used in polyurethane foam molding applications, providing delayed milking time to facilitate mold filling and closing and improve fluidity. Improve production efficiency throughout the foam molding operation.
Dabco 8154 catalyst is also used as a co-catalyst, which can replace 25% of the existing catalyst combination to improve the curing effect without significantly changing the preliminary reaction of the reaction.
Dabco 8154 catalyst can also be used in rigid foam applications, polyurethane insulation boards, polyurethane insulation pipes, polyurethane boards, polyurethane sealants, polyurethane waterproof coatings.
Keep unopened for two years
Storage and transportation:
Should be sealed and stored in a dry, cool and ventilated warehouse
200KG/drum Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the water and other substances from mixing into the product and affecting its performance. Store in a cool, dry place, keep the container sealed and avoid contact with oxides. Do not breathe dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothing separately and wash it before reuse. Maintain good hygiene habits. The company recommends that all polyurethane catalysts be stored in a dry, cool and properly ventilated place. All storage containers must be well sealed to avoid contact with water or other influential substances, because this may change the performance of the product in use. The storage temperature is 10°C to 30°C. Lower or higher temperatures are not suitable and should be avoided as much as possible.
