A solar module includes an edge sealant. The sealant composition includes an unsaturated reactive polyolefin, an olefmic polymer, a silane modified polyolefin, inert fillers, calcium oxide, and aging resistors. These components are balanced to produce a sealant having desirable sealing characteristics, high weatherability, desired rheology, low conductivity, and good water absorption.

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.

An edge seal for manufacturing two-pane or multi-pane insulating glass or solar modules includes a sealant and a bonding agent. The sealant contains a polymer modified with special reactive groups and has the following overall composition: olefinic polymers included in an amount from about 10% to about 90% by weight of the total composition; at least one filler included in an amount from about 10% to about 65% by weight of the total composition; at least one inorganic filler that is a thermal and oxidative stabilizer in an amount from about 2% to about 30%; at least one of a desiccant and a water scavenger included in an amount from about 2.5% to about 25% by weight of the total composition; and at least one aging resistor including an anti-oxidant or UV stabilizer included in an amount from about 0% to about 3% by weight of the total composition.

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:
Various adhesives are described that are resistant to relatively hot aqueous washing solutions and particularly to hot caustic solutions used in bottle washing applications. The adhesives are used to adhere polymeric labels to containers such as beverage bottles and thereby enable the labeled bottles to be subjected to multiple washing operations without label removal or debonding.

A drive assembly for a track-laying vehicle adapted to travel in a horizontal direction along the ground has a horizontally elongated frame having two opposite ends and upper and lower edges extending parallel to the direction between the ends, a drive wheel at one of the ends, a support fixed on the frame between the ends, and a guide on the frame extending between the fixed support and the other end along a line forming an acute angle with the direction and extending downward toward the other end. A movable support displaceable parallel to the line in the guide carries an idler wheel at the other end. A spring braced between the supports urges the idler wheel parallel to the line away from the drive wheel. A plurality of ground wheels are mounted along the lower edge between the drive and idler wheels and an endless track looped around the wheels extends parallel to the direction along the idler wheels. A drive connected to the drive wheel rotates the drive wheel and displaces the track around the wheels.

In order to create a track roller for crawler chains, consisting of a trackoller body, an axle traversing the same as well as bearings and seals arranged between the track roller body and the axle, whereby the axle is affixed to a mount with its ends axially protruding from the track roller body, which has a long life when used as intended, the invention proposes that the bearings (3) radially arranged between the track roller body (1) and the axle (2) be designed as pivoting bearings, so that the load-caused bending of the track roller body or the axle can follow without jamming.

The invention relates to a polymer comprising 50-100% by weight, with regard to the weight of the polymers, of repeating units, which are derived from one or more ethylenically unsaturated ester compounds of formula (I), in which R represents hydrogen or methyl; R1 represents a linear or unbranched alkyl radical with 7 to 30 carbon atoms, and; R2 and R3 independently represent hydrogen or a group of formula —COOR′, wherein R′ represents hydrogen or an alkyl group with 7 to 30 carbon atoms. The polymer is a star polymer with 3 to 21 arms and at least 3 of the arms consist of at least 40% by weight, with regard to the weight of the arms, of repeating units, which are derived from one or more ethylenically unsaturated ester compounds of formula (I), in which R1 represents a linear or unbranched alkyl radical with 7 to 30 carbon atoms, and; R2 and R3 independently represent hydrogen or a group of formula —COOR′, wherein R′ represents hydrogen or an alkyl group with 7 to 30 carbon atoms. The invention also relates to oil formulations comprising the inventive polymers. The inventive polymers having a high thickening action can be used, in particular, as viscosity modifiers, pour point depressants, dispersing agents and/or friction modifiers.
