Properties

• long shelf life
• primerless adhesion to most materials
• non-corrosive to metals
• suitable for alkaline substrates such as concrete, mortar, fibrous cement
• almost odorless
• compatible with water-based and solvent-based coatings: no plasticizer migration
• non-sag
• ready gunnability at low (+5 °C) and high (+40 °C) temperatures
• rapid crosslinking: quickly becomes tack-free
• flexible at low (-40 °C) and high temperatures (+150 °C)
• excellent weatherability

Fields of application

• sealing of connecting and expansion joints for the building industry
• glass and windows construction
• sealing of joints between glazing and supporting structure (frames, transoms, mullions)

Certification

OLV44 is certified and classified according to
ISO 11600 F/G, class 25 LM
EN 15651-1, class 25LM F-EXT-INT-CC
EN 15651-2, class 25LM G-CC
DIN 18545-2, class E
SNJF F / V, class 25E
EMICODE EC1 PLUS

Adhesion

OLV44 exhibits excellent primerless adhesion to many substrates, e.g. glass, tiles, ceramics, enamel, glazed
tiles and clinker, metals e.g. aluminium, steel, zinc or copper, varnished, coated or painted wood, and many plastics.
Users must carry out their own tests due to the great variety of substrates. The adhesion can be improved in many cases
by pretreatment of the substrates with a primer. If adhesion difficulties arise please contact our technical service.
