MetaShieldGLASS is an advanced material surface treatment that meaningfully increases the break resistance of common glass. The liquid based formula is easily applied, and dries within minutes. The patented MetaShieldGLASS formula is effective in increasing the strength of most types of untempered glass up to 5mm in thickness. For example, single strength glass coated with MetaShieldGLASS is actually more break resistant than standard double strength glass. MetaShieldGLASS is a low VOC, water based formula.
