PC-Inject Seal® EP

Two-component low viscosity epoxy injection resin for cracks

PACKAGING

PC-Inject Seal®EP is supplied in packages (A+B) of 1 kg and 3
kg, with components A and B having a fixed proportion by
weight.

PC-Inject® Seal EP is a solvent-free, two-component epoxy system recognized for its remarkable adhesion to both concrete and steel surfaces. This transparent product is acclaimed for its superior compressive and flexural strength, retaining its efficacy even on moist substrates. Its versatility in application ranges from conventional brush methods to advanced one or two-component pressure injection equipment

FEATURES

Solvent-free, low VOC, and non-shrink.
Packaged in pre-proportioned quantities to prevent errors on-site.
Low viscosity for effortless injection into narrow cracks.
Offers high bond strength to concrete, capable of restoring structural integrity.
Hardens effectively at low temperatures, suitable for a wide range of applications.
Exhibits a high heat deflection temperature, making it ideal for high-temperature environments.

USES

Efficiently repairing structural cracks, and sealing fissures ranging from 0.1mm to 10mm, addressing gaps behind tiles or stone facades, affixing steel plates to concrete surfaces, expediting concrete structural restoration, and grouting dowels.

SURFACE PREPARATION

Before initiating the injection process, it is imperative to conduct a thorough examination of the structure in alignment with current industry standards and technological protocols. Subsequently, an injection plan must be meticulously devised. Placement of packers before injection is essential, and it is advisable to conduct a trial injection as a precautionary measure.

APPLICATION PROCEDURE

Resin Injections Procedure:
1. Remove any existing plaster from both sides of the crack and meticulously clean the concrete surface.
2. Seal the crack using PC-Conrend®Plug and install injection nozzles approximately every 20 cm along the crack using the same product.
3. Once the PC-Conrend®Plug has set, commence injecting PC-Inject Seal®EP into the crack by pushing the material through the nozzles,
following these steps:

Position the resin outflow tube (e.g., spirit level tube) in the initial nozzle. For a horizontal crack, initiate from one end; for a vertical crack, start from the lowest nozzle.
Adjust the outflow valve of the compression boiler to inject into the first nozzle until PC-Inject Seal®EP flows out of the adjacent nozzle or until no more pressure can be applied.
Close the first nozzle and proceed with injection through the successive nozzles.
Repeat this sequence until the entire length of the crack has been treated. Allow the material to cure, and the following day, remove (break) the protruding nozzles and reinstate the plaster surface.

MIXING

Components A (resin) and B (hardener) are individually stored in separate containers with pre-established weight proportions for mixing. To commence, the entirety of component B should be combined with component A. The blending process should persist for approximately 5 minutes using a suitable hand tool such as a small trowel. Thorough mixing is paramount, ensuring the hardener is uniformly dispersed by stirring meticulously along the container’s sides and base. If a lesser quantity is necessitated than what is supplied in the package, a ratio of 4 parts by weight of component A to 1 part by weight of component B should be amalgamated in a pristine container following the same mixing procedure.

HEALTH AND SAFETY

PC-Inject Seal®EP incorporates cement powders that, upon exposure to moisture, release alkalis that can pose risks to the skin. To safeguard against these hazards, it is imperative to avoid inhaling the dust and prevent skin and eye contact during usage. Utilize appropriate protective gear such as clothing, gloves, eye protection, and respiratory equipment. Furthermore, the application of barrier creams can offer added skin protection. If skin contact occurs, promptly rinse with copious amounts of clean water followed by cleansing with soap and water. In the event of eye contact, immediately rinse with abundant clean water and seek medical attention. If ingested, seek immediate medical assistance without inducing vomiting.
