Devcon Methacrylate Adhesives Receive GREENGUARD Certification

October 5, 2009

MATERIALS:  Devcon methacrylate adhesives have been certified by the GREENGUARD® Environmental Institute under the institute’s stringent air-quality standards. The adhesives were certified under the GREENGUARD Children & SchoolsSM program as low-emissions building materials suitable for indoor use, including use for educational, healthcare, residential, and commercial environments where children or sensitive adults spend extended periods of time.The certified adhesives - Plastic WelderTM, Plastic Welder IITM, Metal WelderTM, Metal Welder IITM, Composite Welder FSTM, Clear WelderTM, Flex WelderTM and Flex Welder FCTM - offer high-performance bonding for a variety of applications.

These tough, structural adhesives require minimal surface preparation and cure rapidly at room temperature to load-bearing bonds that withstand weathering, humidity, and wide variations in temperature. All offer exceptional flexibility, high tensile and shear strengths, and excellent resistance to peel and impact. Applied with pneumatic or manual applicator guns, Devcon methacrylates are mixed as they are dispensed. Thixotropic nonsagging gels or pastes, they will not run or drip when used on vertical or overhead applications.

Ummm, have you seen this?
Chemical toxicity, indoor air quality, and children's health are serious issues. The overt marketing of misleading claims by Greenguard to uninformed audiences is frightening and unfortunately works against their stated intentions to improve human health.
1. Greenguard claims to be a non-profit; however they share a headquarters and personnel with Air Quality Sciences (AQS), a for-profit testing business owned by Dr. Marilyn Black. Greenguard requires manufacturers to conduct all testing with their for-profit laboratory. This is an obvious conflict of interest, with an unstated focus on profit.
2. Greenguard requirements only address chemicals emitted into air. They do not address toxic content. Much of children's exposure is oral and dermal (through skin).
3. Greenguard/AQS does not publish all details of their requirements and testing methods. There is no independent review or oversight of the technical validity of their requirements. Worse, they imply their "standards" for VOC emissions are approved by the American National Standards Institute (ANSI) which is not true. AQS/Greenguard personnel have full and complete control over the proprietary Greenguard requirements, which they invent and change at will.
4. Greenguard/AQS includes requirements for phthalates, a semi-volatile family of compounds that appear to be endocrine disruptors -- these are the focus of much research and concern. Danish and US research indicates phthalates are showing up in dust, and are not emitted by materials the same way volatile compounds are (volatiles emit faster). Yet, Greenguard uses testing intended for volatiles, which has not been shown to be effective when detecting phthalate exposure. An assurance from Greenguard about phthalates is therefore very misleading.
5. The concentration of a contaminant (amount present in a lungful of air) depends on how much clean air is supplied in a space. Greenguard/AQS uses limits for contaminants based on commercial office and school classroom ventilation rates, which usually have much more clean air supplied. Greenguard does not publish the ventilation conditions for certifying children's furniture for homes and bedrooms. Therefore users have no way to know if the products exceed the stated limits in their own homes.
Why would an organization focused solely on improving public health do these things? As an educated parent I am very concerned.

Light Matters: The Unsung Heroes of Modern Health Care
First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
