Description

YHEpoxy-AD04 is a two-component paste-type repair and leveling material formulated with epoxy resin as the base material, together with a special curing agent, high-strength fillers and additives. After curing, it forms a high-strength, high-density, corrosion-resistant and wear-resistant structure. It is a high-performance material for defect repair, substrate leveling, anti-corrosion protection and surface protection in industrial and construction applications. YHEpoxy-AD04 meets the requirements defined by EN 1504-9 ("Products and systems for the protection and repair of concrete structures - Definitions, requirements, quality control and evaluation of conformity – General principles for the use of products") and the minimum requirements claimed by EN 1504-4 ("Structural bonding").

APPLICATION INSTRUCTIONS

Substrate preparation: Grind the substrate to expose the sound concrete base. The surface must be clean and free from oil, dust, dirt and other impurities.
Pre-mixing of components: Before using the two-component epoxy putty, stir Part A and Part B separately until each component is uniform.
Putty preparation: Accurately weigh the pre-mixed Part A and Part B according to the specified mixing ratio, then mix the two components thoroughly. The mixing time shall not be less than 2 minutes.
Application: Apply the prepared epoxy putty in the normal way. Manual trowel application may be used.
The amount prepared each time should not be excessive. The mixed putty must be prepared and used immediately.
Important note: Under high-temperature conditions in summer, the curing speed is faster. The epoxy putty should be mixed according to the actual application progress, and the prepared putty must not be left standing for a long time.

TRANSPORTATION AND STORAGE

Storage conditions: Store at 5°C–35°C in a cool and dry place.
The product is non-flammable and non-explosive. Ensure ventilation during application and wear protective gloves.
Epoxy Putty is a non-dangerous product and can be transported as general chemical construction material.

HEALTH AND SAFETY

When the product reacts, it generates considerable heat (or low amount, depending on the product). After mixing components A and B, we recommend applying the product as soon as possible and never leaving the container unattended until it is completely empty. The product must be handled properly. Users shall refer to the latest Material Safety Data Sheet (MSDS) containing physical, ecological, toxicological and other safety-related data for information and advice on safe handling, storage and disposal of chemicals.

Scope of Application

Suitable for surface protection of new concrete structures, repair and protection of existing buildings, and anti-rust protection of steel structures, including:

Waterproofing treatment of wide joints;
Rigid structural bonding of prefabricated concrete elements;
Sealing of large cracks in industrial floors subject to traffic;
Bonding of slabs and pipes in concrete and fibre-reinforced concrete;
Bonding of steel to concrete;
Bonding of metal or TPE drains.
