摘要:
A polyblend of a high graft copolymer, a low graft copolymer and a matrix interpolymer is made by:(A) mixing a latex of the high graft copolymer and a latex of the low graft copolymer to provide a mixture thereof;(B) coagulating and at least partially dewatering the mixture of step (A);(C) melt blending the mixture of step (B) to provide a first polyblend; and(D) melt blending the first polyblend of step (C) with matrix interpolymer to provide a second polyblend.
摘要:
Seal a fenestration opening that contains a gap having a width of greater than 1.6 millimeters by providing a dispersion having the following components dispersed in an aqueous phase: (i) a film-forming polymer binder having a glass transition temperature in a range of −100 degrees Celsius to −20 degrees Celsius; (ii) a shear thinning rheology modifier at a concentration sufficient to cause the dispersion to have a Brookfield viscosity greater than 300,000 centiPoise as measured using spindle #3 at 0.3 revolutions per minute; and (iii) optionally, a filler; and then spraying the dispersion directly onto the building elements within the fenestration opening so as to form a continuous coating over the building elements and gap within the fenestration opening; wherein there is an absence of reinforcement or sealing material filling or spanning the gap prior to spraying the dispersion over the gap.
摘要:
A floating dock system contains a polymeric foam core, a structural collar, attachment means connected to the structural collar and a protective coating adhering to and completely covering the polymer foam core and structural collar and is free of decking or plates that are independent of the structural collar between the top surface of the polymeric foam core and the protective coating.
