    • The disclosed latex system comprises a one-component, closed-cell, semi-foam, mastic sealant using gas-filled, flexible, organic microspheres to create a product that is elastic and compressible under pressure without protruding in an outward direction when compressed, thereby allowing the applied sealant to compress in an enclosed, maximum- filled channel unlike typical mastic sealants (while retaining the ability to rebound). This allows the sealant to function as a gasket, and, once fully cured, to have properties including vibration damping, insulating, and condensation resistance. The sealant can be formulated as an air barrier or a vapor barrier and at various degrees of moisture resistance. It may be applied by different packaging variations including aerosol can (bag in can or bag on valve), airless sprayer, cartridge tubes, foil tubes, squeeze tubes, and buckets to be applied using a brush, trowel, spatula, etc. The disclosed mastic sealant can also be formulated to be smoke-resistant and flame-resistant.
    • 所公开的乳胶体系包含使用气体填充的柔性有机微球体的单组分闭孔半泡沫乳香密封剂,以产生在压力下弹性且可压缩而不突出的产品 在压缩时沿向外的方向,从而允许施加的密封剂在与典型的密封胶(与保持反弹能力)不同的封闭的,最大填充的通道中压缩。 这允许密封剂起到垫圈的作用,并且一旦完全固化,就具有包括减振,绝缘和抗凝结性能的特性。 密封剂可以配制成空气阻隔层或防潮层,并且具有不同程度的防潮性。 它可以通过不同的包装变体来应用,包括使用刷子,t刀,抹刀等施用的气雾罐(罐中的袋子或袋子上的袋子),无空气喷雾器,筒管,箔管,挤压管和桶。所公开的 乳香密封胶也可配制成耐烟和阻燃的。
