    Application A33 The basic ingredient is proven in the production of foam in a safe and reliable Triethylene diamine. It isobutyl ester chloride / water reaction can play a catalytic role, as long as the appropriate adjustment, A33 can achieve security and a wide operating range. Although A33 is proved for the production of flexible foam excellent tool, but in fact, it can be extended to the application of rigid PU foams, microporous PU foam and PU coating. But the recipe in this leaflet is mainly suitable for heat-curing foam and high resilience foam only.   In the traditional application of soft foam A33 The biggest advantage is to make the production of safe, greatly reducing the breakdown of the situation, even in the use of organic foaming agent formulations, foam was still able to have a good solidification, from the top to the bottom has a uniform density distribution and a large number of openings cell. 20-30kg/m3 density formulations, A33 can be used alone or in combination with an auxiliary amine such as used in conjunction DMEA. If only the formulations A33, reference to the amount available in the amount of 0.15-0.25pbw also possible. Reference formula in the chart a course to identify the most appropriate dosage formulation, machine conditions, the activity and silicone materials selection is bound to consider. If necessary the enhanced foaming formulations 35kg/m3d reaction A33 except that addition, DMEA or most suitable for PMD, and A33 are used in a proportion of 1:1 to 1:3.   Exhibit 1 (All percentages by weight)
