Teknobond 310 is a two-component epoxy primer with low viscosity and special additives to improve adhesion and strength, without solvents.
APPLICATION
● For priming concrete surfaces and cement screeds to strengthen them.
● For priming surfaces before applying epoxy and polyurethane topcoats.
● To improve surface adhesion to leveling compounds and epoxy-based coatings
● To reduce the absorbency of the surface to reduce the cost of surface coating.
● Can be used on both dense and highly absorbent surfaces to strengthen them.
● Can be used as a rough ground, leveling/filling irregularities and cracks on the surface, provided that quartz sand is added in a ratio of 1:0.5 or 1:08 (Quartz sand: Teknobond 310).
FEATURES / ADVANTAGES
● Has low viscosity.
● Has high adhesive strength.
● Has high penetrating ability.
● Short intercoating time.
● Simple to use, easy to apply.
● For indoor and outdoor use.

APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PREPARATION
The surface must be free from dust, dirt, loose particles, cement mortar residues, oils, silicones and must be dry. The concrete base must be clean, strong and have sufficient compressive strength (at least 25 N/mm²) and tear strength of at least 1.5 N/mm². Damage, cracks, potholes on the concrete surface must be repaired in advance using appropriate cement (Teknorep/Teknogrout/Teknoself) or epoxy (Teknobond 400D/405D) repair mixtures.
KNEADING
● Add component B to component A.
● Mix both components with a low-speed electric mixer (maximum 400 rpm) for 2–3 minutes until smooth.
● Mix the material in the amount you can use, according to the proportion specified by the manufacturer.
CAUSING
Make sure that TEKNOBOND 310 is applied to a solid and thoroughly cleaned surface. The material can be applied with a brush, roller or squeegee.
CLEANING THE TOOL
Clean tools and equipment with water immediately after use. Once the material has cured, it can only be removed mechanically.
LIMITATION
● Do not use at temperatures below the minimum and above the maximum permitted
● Low temperatures slow down hardening, high temperatures accelerate it.
● Do not add foreign substances to the product.
● The component ratio is precisely calculated, do not use less/more of component A or B.
SAFETY MEASURES
The product may cause irritation if it comes into contact with the skin. It is necessary to use work clothes, protective gloves, a mask and glasses. You can also apply a protective cream to your hands before starting work. In case of contact with eyes, immediately rinse your eyes with warm water and consult a doctor.
MATERIAL DATA BASIS
The above technical data are obtained from laboratory tests conducted at a temperature of + 20 °C and a relative humidity of 50% in the Tekno Yapı Kimyasalları laboratory. The results are obtained 28 days after the tests. The actual characteristics of the material may change for reasons beyond our control. Since we are unable to control the installation process and operating conditions, we are only responsible for the quality of the material. The production of materials is periodically optimized and improved, we have the right to make changes to the technical description of the materials without informing the customer.
