Adhering to Difficult Substrates with Silicone Adhesives

Substrates with reactive groups available for bonding make chemical bonding easier to achieve, while substrates with nothing to react to make adhesion difficult.
October 1, 2005
Adhesive technology is equal parts chemistry and "black magic." The sheer number of available substrates makes it nearly impossible to test each adhesive on every type. However, by conducting tests on a selection of novel, or difficult-to-adhere-to, substrates, we can make inferences that may help narrow the choice of adhesives.

U.S. Sealant Standards in Building Construction

Sealants must be applied according to the manufacturer’s instructions, which generally correspond with industry guides and practices.

Standards are an important aspect of your business. If you manufacture, purchase, or use sealants or if you supply raw materials for sealants, your company relies on standards every day. R&D uses test methods and specifications to characterize, compare and develop products. Marketing and Sales use these same standards to advertise and promote products. When materials or sealants are purchased, they must comply with specifications.

Pressure-Sensitive Adhesive Testing

Testing pressure-sensitive adhesives under standard conditions of temperature and relative humidity is always a preferred means to compare data from lab to lab and from lot to lot, but it is sometimes necessary to evaluate the performance of an adhesive under conditions that it would encounter in the field.
September 11, 2000
Many adhesives exhibit different properties when subjected to variations in temperature. Some of these adhesives are thermoplastic. They soften when heated and become more brittle when cooled. [In the case of pressure-sensitive adhesives (PSAs), the nature of the bond is nearly always thermoplastic.] If for the sake of this discussion we limit our testing to tack, peel and shear, we can develop a series of observations that can be applied to most testing situations.

ISO 9000:2000 - The New Quality Standard

ISO 9000 has been revised—but the new standard, called ISO 9000:2000, is a radical revision and the industry has questions.
April 17, 2000

In view of the impact of this revision and the costs it will entail, organizations understandably have many questions and concerns. Do we have to register to the new standard? How long is our current certification good for? Why the change? What’s the difference between the old ISO and the new ISO? How will it change the way we run our business? Who will benefit from the new standard? Who will be hurt? Will it be more difficult to implement the new ISO than the old ISO?
