A pitch pocket assembly for sealing an aperture in a roof includes a first member and a plurality of flashing members. The first member includes a wall portion and a plurality of flashing portions. The plurality of flashing portions extend from and are substantially perpendicular to the wall portion proximate at least one deformation zone. The plurality of flashing members are each attached to the first member. Each of the flashing members at least partially overlaps at least one of the flashing portions. The wall portion of the first member is bendable along each of the deformation zones to form a pitch pocket having the flashing members at least partially overlapping the flashing portions of the first member.

A solar module includes a photovoltaic device that has an edge seal. The sealant composition of the edge seal includes an unsaturated or reactive polyolefin, an olefinic polymer, a silane modified polyolefin, inert fillers, a water scavenger or desiccant, an antioxidant, and a UV stabilizer. These components are balanced to produce a sealant having desirable sealing characteristics, high weatherability, desired rheology, low conductivity, and good thermal stability.

A system and method for applying a two-part adhesive to a substrate includes a prime mover for providing an output torque, a first pump connected to the prime mover for receiving the output torque, the first pump having an inlet and an outlet, a second pump connected to the prime mover for receiving the output torque, the second pump having an inlet and an outlet, a first compound in communication with the inlet of the first pump, a second compound in communication with the inlet of the second pump, a first accumulator in communication with the outlet of the first pump, a second accumulator in communication with the outlet of the second pump, a first manifold in communication with the outlet of the first pump, and a second manifold in communication with the outlet of the second pump.
摘要:
A package for holding a part of a two-part adhesive that is applied to a substrate includes a collapsible bag, an end cap attached at a first end of the bag, and a spout attached to a second end of the bag. As pressure is applied to the end cap, the part of the two-part adhesive is forced out of the spout.
摘要:
A sealant composition which may be applied between two substrates in a solar panel provides consistent rheology, high weatherability, acts as a moisture barrier, and has low conductivity. The sealant composition preferably includes a rubber component, at least one rheology modifier, an adhesion promoter, a flow modifier, a stabilizer, and a high level of carbon black.
摘要:
This invention relates to an edge seal for manufacturing two-pane or multi-pane insulating glass or solar modules, there being provided a primary sealant and a secondary sealant.To create a sealing compound with which permanent stability of the edge seal can be obtained, even under high stresses, it is suggested within the scope of the invention that the primary sealant contains a polymer modified with special, reactive groups and has the following overall composition: a) 30-60 wt. %, preferably 40-50 wt. %, olefinic polymers, Mn 400-600,000 D, preferably 5,000-300,000 D b) 2-35 wt. %, preferably 5-25 wt. %, modified polymer c) 5-40 wt. %, preferably 10-30 wt. %, fine-particle, inert fillers d) 5-25 wt. %, preferably 10-15 wt. %, desiccants and water scavengers 0-3 wt. % aging resistors, in particular anti-oxidants or UV stabilizers, and that the secondary sealant is a silicone-based sealant. The sealing compound and the silicone secondary sealant together produce a seal which is substantially more stable toward external influences (e.g. plasticizer migration from incompatible materials), even at high temperatures and under exposure to alternating temperatures.

摘要:
A recreational or large vehicle windshield cover is disclosed and comprises: a) a windshield cover component having a bottom portion, a top portion, a left side and a right side, b) at least two strap components coupled to the bottom portion of the windshield cover component, and c) at least one strap component coupled to the top portion of the windshield cover component. Methods are also contemplated of using a recreational or large vehicle windshield cover, comprising: providing a windshield cover component having a bottom portion, a top portion, a left side and a right side, at least two strap components coupled to the bottom portion of the windshield cover component, and at least one strap component coupled to the top portion of the windshield cover component; providing a recreational or large vehicle; securing the top strap component to the top of the recreational or large vehicle; and securing the at least two strap components coupled to the bottom portion of the windshield cover component to the side of the recreational or large vehicle.
摘要:
A two part adhesive packaging system is provided. The packaging system includes two containers for holding a two-part adhesive. The packaging system further includes a connector having two ports for communicating with the containers. A membrane is adhered overtop the ports to prevent the two-part adhesive from draining from the containers. The membrane is configured to break upon application of a sufficient force thereon, such as by pumping or pushing the two-part adhesive from the containers.
