Abstract: The subject invention is based upon the unexpected discovery that the use of a very specific combination of hydrophobating silanes and sulfur crosslinkable silanes can be used to attain outstanding performance characteristics in silica reinforced rubber formulations. More specifically, these rubber formulations provide a highly desirable combination of both improved abrasion characteristics and reduced hysteresis without compromising other important rubber characteristics. The present invention more specifically discloses a sulfur cured rubber formulation which is the reaction product of (1) at least one rubbery polymer, (2) sulfur, (3) silica, (4) 2 phf to 12 phf of a hydrophobating silane, and (5) 0.5 phf to 3 phf of a crosslinkable silane. The weight ratio of the hydrophobating silane to the crosslinkable silane will typically be within the range of about 2:1 to about 20:1.

Abstract: A particle and a method for producing the same is disclosed. For example, the particle includes a polymer resin that is compatible with a three-dimensional (3D) printing process to print a three-dimensional (3D) object and a marking additive that allows selective portions of the 3D object to change color when exposed to a light, wherein the marking additive is added to approximately 0.01 to 25.00 weight percent (wt %).
Abstract: As the sealant material composition forming a sealant layer of a pneumatic tire provided with the sealant layer on a tire inner surface, the sealant material composition prepared by blending from 0.1 parts by mass to 20 parts by mass of a crosslinking agent, from 0.1 parts by mass to 40 parts by mass of an organic peroxide, and from 10 parts by mass to 400 parts by mass of a liquid polymer per 100 parts by mass of a butyl rubber is used.
Abstract: A paint composition contains (A) a binder component, (B) a first rheology control agent, and (C) a second rheology control agent, wherein the first rheology control agent (B) contains a reaction product of (b1) a polyisocyanate compound, (b2) a primary monoamine having a number average molecular weight of 300 or less, and (b3) a polyether amine having a number average molecular weight of more than 300 and less than 6000; the proportion of the polyether amine having a number average molecular weight of more than 300 and less than 6000 (b3) is 0.
Abstract: The present invention pertains to reactive (moisture curing) plasticizers; adhesives and sealants containing the plasticizers and methods of bonding and sealing substrates with adhesives and sealants containing the plasticizers.
