摘要:
Fibers comprising a first thermoplastic composition having a softening temperature up to 120°C and a curable resin. Also disclosed are compositions comprising a plurality of fibers, with some of the fibers comprising a first thermoplastic composition having a softening temperature up to 120°C and some of the fibers comprising a curable resin. The fibers have an aspect ratio of at least 2:1 and a maximum cross-sectional dimension up to 60 micrometers. Fluid compositions containing the fibers and methods of contacting a subterranean formation using the fibers are also disclosed.
摘要:
There is provided a one -part curable epoxy composition comprising a heat curable epoxy resin; and a latent curative system in an amount sufficient to cure the epoxy resin, where the latent curative system comprises at least one epoxy resin miscible first curative comprising a latent hardener, selected from dicyandiamide and its derivatives, and two or more latent accelerators selected from at least one of substituted ureas, substituted imidazoles, and combinations thereof. There are also provided adhesive compositions, cured adhesives and articles made using such one-part curable epoxy compositions.
摘要:
Methods of preparing silicone pressure sensitive adhesives are described. The methods include applying a composition comprising a nonfunctionalized polysiloxane material to a substrate and crosslinking the nonfunctionalized polysiloxane by exposing the composition to electron beam irradiation, wherein the nonfunctionalized polysiloxane material is a nonfunctionalized polysiloxane fluid having a dynamic viscosity of no greater than 1,000,000 mPa€¢sec at 25 °C.
摘要:
Methods of electron beam curing nonfunctional polysiloxanes and silanol terminated polysiloxanes are described. The resulting release materials are also described.
