PROPERTIES
Single component adhesive based on modified polyvinyl dispersion (vinyl acetate), waterproof class D4 according to PN-EN-204. At full strength, the seam has very good adhesion to wood surfaces under static as well as dynamic loading, and also has good initial adhesion. The adhesive has a certificate issued by IFT Rosenheim confirming class D4 according to the PN-EN 204 standard, as well as high thermal resistance: ≥ 7 N/mm2 according to EN 14257 (WATT`91).
APPLICATION
- natural wood for gluing during the manufacture of wood products for interior construction
- interior elements particularly exposed to moisture,
- exterior elements with appropriate surface protection
- bonding softwood
- bonding hardwood
- bonding floor panels
- bonding chipboard or fibreboard
- bonding plywood
- bonding other wood-based materials
- for use in cold pressing and manual bonding
- for use in hot pressing, chipboard and MDF
- for bonding plywood and laminates
- not recommended for external elements subject to intense exposure to moisture, such as doors or garden furniture, etc.
INSTRUCTIONS FOR USING THE ADHESIVE
Material preparation
The surface prepared for bonding must be dry, clean and free from dust, oil and grease residues which could reduce adhesiveness. Wood moisture should be 10 ÷ 14 [%]. The elements for gluing should be adapted to each other.
TECHNICAL DESCRIPTION
Dry matter content 51 ± 3 [%]
Brookfield RV adhesiveness 5,500 ± 1,500 [mPa·s]
PARAMETERS
pH approx. 3
MTTF approx. 6 [°C]
Durability after 25 min. Min. 4 [MPa]
Seam Colourless, flexible, does not damage tools, ageing resistant
Density 1.05 g/cm3
Application of adhesives
It is recommended to mix the adhesive thoroughly before use. The adhesive can be applied on one or both sides with a brush, trowel, spray bottle, applicator, hand roller or equipment (nozzles or rollers). The recommended amount of adhesive to be applied, depending on the type of base, is:
- surface bonding: 80 ÷ 120 [g/m2]
- mounting bonding: 120 ÷ 150 [g/m2]
- bonding wood for windows: 150 ÷ 200 [g/m2]
Discolouration
The adhesive does not affect the discolouration of the wood, but it is recommended not to use iron tools when working with the adhesive, as contact with wood containing tannin can lead to discolouration.
Open time
Open time: 3 ÷ 10 [min]. The open time depends on the type of wood, porosity, amount of applied adhesive, humidity and air temperature, adhesive and glued elements.
Bonding temperature
Use at 15 [°C] ÷ 30 [°C]. This affects the ambient temperature and above all the temperature of the materials to be glued and the adhesive itself.
Pressing
– pressing pressure
in the range 0,1 ÷ 1,2 [N/mm²] depending on the stresses present in the materials to be bonded. When applying adhesive manually, press the surfaces to be joined in such a way as to lead to the release of excess adhesive.
– pressing time
depends on the type of wood and its moisture content, temperature and humidity, as well as the amount of adhesive applied and the stresses present in the materials to be glued. Press the elements to be glued until durability is reached, when further processing or transportation is possible.
– suggested average pressing time
cold pressing over 20 [min]
hot pressing 2 ÷ 10 [min] (depending on the press temperature)
Good bonding results can be achieved when:
- Bonding process temperature is 15 ÷ 25 [°C]
- Relative air humidity 40 ÷ 70 [%]
- Wood moisture content 10 ÷ 14 [%]
- Quantity of adhesive applied 80 ÷ 200 [g/m2]
- Maximum open time 3 ÷ 10 [min]
CLEANING
Tools should be washed in water as soon as the work is finished. Do not allow the adhesive to dry. Remove the dried adhesive from the tools mechanically, before soaking in hot water (about 1 hour).
STORAGE
Store in original, tightly sealed containers at +5 to +30 [°C]. The product stored in such conditions retains its properties within 6 months from the date of manufacture.
