Addressing Formaldehyde Risks
Formaldehyde is classified as a CMR substance, posing long-term health risks to both production workers and end-users. Traditional adhesives release formaldehyde not only during manufacturing but also throughout the product's entire service life. ResiCare's bio-based, formaldehyde-free resin solutions eliminate this risk entirely, offering the most reliable path to compliance and personnel safety.
