webertec 793 Universal Construction Resin Reaction Resin Mortar Reaction Resin Epoxy Resin

Universal reaction resin binder for the production of reaction resin mortar concrete, bonding agents, adhesives, and coatings

Application Area

webertec 793 is suitable as a binder for reaction resin mortar as well as for bonding agents, adhesives, and coatings

Product Description

webertec 793 is a two-component transparent reaction resin based on epoxy resin

Composition

Epoxy resin

Product Properties

• High solid content
• High compressive, flexural, and adhesive tensile strength
• Excellent adhesion to concrete and screed
• Can be used on dry or slightly moist substrates
• Resistant to many diluted acids and alkalis
• Resistant to animal and plant oils and fats
• EMICODE EC 1 – very low emissions

Color: Transparent

Storage: When stored dry in the original sealed container, the material is storable for at least 24 months

Consumption

Coverage per coat: approx. 200 – 400 g/m²

Bonding agents: approx. 400 – 700 g/m²

Reaction resin mortar with 1 part resin and 4 parts sand at 10 mm layer thickness: approx. 29 kg/m²

Substrate Preparation

The substrates must be sufficiently load-bearing, clean, dry, dimensionally stable, and free of substances that impair adhesion. Loose or peeling mortar and paint residues should be carefully removed. Suitable pretreatment methods include blasting, shot blasting, etc.

Processing

Mixing

For two-component reaction resins, the amount of component B is matched to component A. Partial quantities should be avoided. Completely empty component B into component A. Mix in a container of component A with a slow-running drill and paddle mixer No. 2.8, ensuring to include edges and bottom areas. Mixing time approx. 2 minutes until a homogeneous, streak-free mass is achieved. To prevent residual sticking of component B, transfer the mixed material to another container, stir briefly, then return to the original container, and stir again.

Reaction Resin Mortar

Mix dry quartz or Rhine sand in a ratio of 1 RT resin : 4 RT sand. Layer thickness: 6 mm to 20 mm. Due to the material's viscosity, forced mixers are recommended. After application, smooth the mortar to the desired layer thickness.

Repair of Damaged Structures

Prime with weberprim 807. Bonding agents with webertec 793 are applied, and fresh mortar is applied immediately from 1 RT webertec 793 and 3 to 5 RT quartz sand. For depths up to 2 cm, roughening is 0 to 4 mm; for depths over 2 cm, roughening is 0 to 8 mm.

Coating

Prime with weberprim 807. A 1- to 2-layer topcoat is applied on the still tacky primer. The waiting time between coats should be such that the previous coat remains tacky when the next is applied. Excessive scattering of quartz sand on the coating allows longer intervals and increases adhesion. Depending on the substrate, application amount, temperature, and air circulation, reworking time can be approx. 0.5 to 10 hours.
