REZI-WELD LV

LOW VISCOSITY INJECTION EPOXY
Provides a low-viscosity, easy-flowing injection epoxy in a unique, unitized package.

SEALTIGHT REZI-WELD LV Low Viscosity Injection Epoxy is a two-component, easy-flowing, low-viscosity structural epoxy adhesive suitable for pressure injection of cracks, and as a binder for a wide variety of maintenance, repair and concrete rehabilitation patching and grouting applications.

Technical Description
SEALTIGHT REZI-WELD LV Low Viscosity Injection Epoxy is 100% solids, moisture insensitive, very low viscosity, high modulus, and high strength structural injection resin. REZI-WELD LV is V.O.C. compliant and resists most chemicals.

REZI-WELD LV features a unique and innovative unitized packaging concept. It combines two color-coded, pre-measured, components into an easy-to-handle, single unit along with a handy, wood mixing paddle. The unitized packaging eliminates mishandling and mismatching of the components on the jobsite.

Uses
REZI-WELD LV is designed for gravity feeding or pressure injecting using two-component metering systems, hand-held bulk guns or pressure pots. It is suiable for injecting fine, non-moving structural cracks for permanent repairs.

When mixed with sand or aggregates REZI-WELD LV makee an economical, easy-to-use epoxy mortar for patching or repairing defects in concrete substrates, securing machinery base plates to concrete floors, interior non-skid pathways and structural bonding applications.

Application
SURFACE PREPARATION: All surfaces to be bonded must be free of standing water and completely clean of dirt, rust, curing compounds, grease, oil, paint, waxes and other materials which would prevent a maximum bond.

Concrete should be cleaned by mechanical abrading or sandblasting to a sound surface. Vacuum or blow dust away with compressed air. Mechanically abrade metal base plates to a bright metal finish.

Exposed steel surfaces should be sandblasted and vacuumed clean; if not possible, degrease the surface and use sandpaper or a wire brush to reveal continuous, bright metal.

MIXING NOTE: Condition all components to 60-85F for 24 hours prior to use. Pre-mix each component. Mechanically mix at slow speed (600-900 rpm) using a drill and Jiffy Blade or drum mixer to 3 minutes or until completely mixed while scraping the sides to ensure complete blending of components. Avoid air entrapment. Mix only very small quantities by hand for a minimum of 3 minutes or until sufficiently blended together using the supplied stirring stick. Scrape the sides of the container to ensure complete blending of components. Mix only the amount of epoxy that can be applied within the product's potlife. Potlife will decrease as the ambient temperature and/or mass size increases.

INJECTION: Epoxy can be gravity fed into horizontal cracks that are small, (1/4" [6.35mm] maximum width) and have a limited depth. For large injection projects, a self-proportioning, mixing and pressure injection equipment is recommended. For small injection projects, SEALTIGHT REZI-WELD RAPID SET PRE-PAK self-contained, barrier-type cartridge may be suitable.

INTERIOR, NON-SKID PATHWAYS: For thin applications, apply at a rate not to exceed 110 ft. per gallon (2.70m/liter). For heavy coverage, apply layer of sand or grit over epoxy and allow to set. Blow excess sand away. NOTE: REZI-WELD LV IS NOT TO BE USED AS A FINISHED FLOOR COVERING OR PROTECTIVE TREATMENT.

AGGREGATES FOR EPOXY-RESIN MORTARS: Combine clean, dry aggregates with freshly mixed epoxy in a ratio of 1 part epoxy to 1 to 4 parts, by volume, of graded aggregates. Patch thickness should not exceed 1-1/2" (38.1mm) per lift.

CLEANUP: Clean tools and equipment immediately with Toluene avoiding heat, sparks, open flame, breathing vapors or allowing epoxy-containing solvent to contact skin. Never wash hands with solvent.

Specifications
ASTM C 881, Type I, II, IV and V Grade 1, Class B & C
AASHTO M 235 Type I, II, IV and V, Grade 1, Class B & C
USDA Accepted

Shelf Life
Two years in unopened, damage-free containers stored in a dry environment between 40 and 95F (4 and 35C).

Coverage
One gallon (3.8 liter) neat covers approximately 85-110 ft. (2.09-2.70 m/liter) depending on the surface porosity and end use application. One gallon (3.8 liters) mixed 1:1 with dry aggregate yields approximately 350 in. (5.135.45cm) of grout.

Precautions
DO NOT DILUTE. Mix complete units only. The epoxy must be between 60 and 85F (16 and 29C) at time of mixing. Warm by placing containers into hot water. The preferred method is to store the epoxy in a warm room prior to use. Surface substrate temperature must be between 40 and 90F (4 and 32C). Do not seal cracks while under hydrostatic pressure.

REZI-WELD LV is not to be used as an exterior coating as it is not resistant to ultraviolet rays. This epoxy is corrosive. Personal protective equipment is necessary. Unused epoxy will generate excessive heat, especially in large quantities. Unused epoxy should be mixed with dry sand in the container to help lower the heat. Read and follow application information, precautions and Material Safety Data information.
