摘要:
A pressure-sensitive adhesive composition includes a β-1,3-glucan derivative obtained by introducing an acyl group into a β-1,3-glucan, the β-1,3-glucan derivative having a degree of substitution of the acyl group of 2.6 or more and less than 3.0, and a compound having both of a (meth)acryloyl group and a hydroxyl-group-reactive functional group, and/or a reaction product of the β-1,3-glucan derivative and the compound having both of a (meth)acryloyl group and a hydroxyl-group-reactive functional group; and a photo-radical generator.

The present invention further provides a binder composition comprising a first binder and a second binder, wherein the first binder comprises, by dry weight based on total dry weight of the binder composition, from 5% to 98% polymer particles, from 0.3% to 20% a first polysaccharide, and from 0.1% to 20% a colorant; and the second binder comprises, by dry weight based on total dry weight of the binder composition, from 0.05% to 5% a crosslinker. The present invention further provides a paint formulation comprising the binder composition.
摘要:
Tyres for vehicle wheels having reduced environmental impact and the components thereof, in particular reinforcing structural elements such as carcass structures, belt structures, flippers and chafers, include elongated reinforcing elements treated with resorcinol and formaldehyde-free cross-linkable adhesive compositions. The adhesive compositions include at least a) a rubber latex, at least b) an epoxide and at least c) a polyamine with molecular weight higher than 190 Daltons, including at least two amino groups selected from primary —NH2 and secondary —NH— amino groups. In the structural element, these compositions confer an adhesion between cords and compounds that is comparable to, if not better than, the traditional RFL system in use in this sector. Furthermore, by suitably modifying the compound compositions in the reinforced structural elements and, possibly, also in the other elastomeric components of the tyre, it is possible to manufacture tyres while avoiding the use of toxic chemicals, such, as resorcinol and formaldehyde.
摘要:
The present invention relates to an aqueous binder composition and a method for binding fibrous materials by using the same, and more specifically, relates to an aqueous binder composition and a method for binding fibrous materials by using the same comprising one or more reducing sugars, one or more amino acids, and one or more ionic compounds including metal cation having oxidation number of 2 or higher. The present invention provides the same or better physical properties with lower price compared to traditional phenol formaldehyde resin (PFR), does not include or release toxic materials such as formaldehyde or phenol, and may decrease intoxication which is a vulnerable point of traditional PFR during manufacturing and remarkably enhances the mechanical properties such as water resistance, tensile strength and hardness of the manufactured product.
