Abstract:
The present invention relates to a curing agent for moisture-curing compositions which includes at least one aqueous emulsion of at least one epoxy resin. Curing agents according to the invention are especially used for the accelerated curing of moisture-curing compositions which are based on polyurethane polymers that have isocyanate groups or of silane-functional polymers.
Abstract:
To provide a fluorinated ether compound, a fluorinated ether composition and a coating liquid, whereby it is possible to form a surface-treated layer which has high initial water/oil repellency and which is excellent in abrasion resistance and fingerprint stain removability, and a substrate having a surface-treated layer and a method for its production.A fluorinated ether compound which has a poly(oxyperfluoroalkylene) chain ((αβ)n) made of at least two units (αβ) linked to one another, and which has a hydrolysable silyl group on at least one terminal of the chain ((αβ)n) via a linking group, wherein each unit (αβ) is a poly(oxyperfluoroalkylene) group comprising one to three groups (α) made of at least one type of a C1-2 oxyperfluoroalkylene group and one to three groups (β) made of at least one type of a C3-6 oxyperfluoroalkylene group.
Abstract:
Raw materials that constitute reaction products of two compounds (1) and (2) having the general formulas (1) and (2), wherein the first compound (1) having the general formula (1): R1—(CH2)a—(CHR2)b—(CR32)c—(CHR4)d—(CH2)e—R5, and the second compound (2) has the general formula (2): Y-A-Si(OR1)r(R2)3-r, exhibit anti-wrinkle properties. They are used in laundry detergents, fabric softeners or textile treatment compositions that are applied to the textile outside a washing machine or a dryer.
Abstract:
A method and kit for forming a seal around a roof penetration is disclosed. The method comprises dispensing a one-part moisture curable sealant into pitch pan formed around a roof penetration. The one-part moisture curable sealant contains a polymer having non-terminal silane groups. The incorporation of non-terminal silane groups can provide for a greater number of crosslinking points than terminal silane groups. The non-terminal silane groups can be placed at specific points along the polymer backbone and the number of crosslinking points, or concentration of crosslinking units, can be controlled. Generally, as the crosslinking points can be provided along the polymer chain, the number of crosslinking points is increased, especially as compared to polymers only having terminal silane groups. Increasing the number of crosslinking points can result in improved elasticity and cure-through as compared with silyl-terminated polymers, in addition to other advantages.
Abstract:
A novel composition for use as a print head face plate coating. In particular, the coating comprises siloxyfluorocarbon (SFC), which is composed of networked precursors containing reactive siloxane groups attached to fluorocarbon chains. The present SFC coatings can be used to produce a surface whereby solid ink and ultraviolet (UV) curable inks do not adhere when applied at elevated temperatures and over an extended period of time. The advantages of the present coating are fewer print head related defects, and longer front face life.
