SikaWrap Hex- 430G (VP)/Sikadur

- 330

Glass Fiber Fabric Strengthening System

Description Externally applied Strengthening or Repair system for structural members made ofreinforced concrete, masonry or timber

System components :Glass fiber fabric SikaWrap Hex-430G (VP) and epoxy based impregnating resinSikadur-330

Uses Strengthening of reinforced structures, masonry and timber in case of flexural and

shear load due to :Increase of loading capacityChanges of building utilisationRepair of defectsPrevention of defects caused by earth quakesMeeting of changed standards or specifications.

Advantages Multifunctional use as bending or shear reinforcementThixotropic, solvent free impregnating resin for easy use on siteFlexibility of surface geometry (Beams, columns, chimneys, piles, walls).Resistance against chemicals and environmental condition (no corrosion)Fabric available in 2 widths for optimum utilisationThin coating even with layers of fabric (application up to 3)Fibre orientation tailor-made

ApplicationCutting to size The fabric can be cut with a special scissors or a very sharp knife, but may neverbe folded!

Surface preparation Preparation of the substrate by sandblasting or grinding., Subsequently anydust or loose particles must be removed by means of an industrial vacuumcleaner. The substrate must be clean, free from grease and oil and should bedry (max. moisture content of substrate 4%).The surface to be bonded must be level, with steps and form work marks notgreater than 0.5 mm. Larger unevenness must be levelled using Sikadur 41 ora mixture of Sikadur-30 and quartz sand Sikadur-501 (mix ratio 1:1 parts byweight).The adhesive tensile strength of the substrate to be reinforced must be at least1.0 N/mm2Structural corners must be rounded to a radius of at least 10 mm.This can be achieved using a diamond grinding disk.

Mixing First, mix the material in each container separately. Then add component B tocomponent A, ideally using the special Sika Spatula. Stir with an electric mixer forapprox. 3 minutes until all the coloured streaks have disappeared. Then, pour thewhole mix into a clean container and stir again for approximately 1 minute at lowspeed to keep air entrainment at a minimum.Potlife starts with the mixing of both components (resin and hardened). At lowambient temperature it will be longer, at elevated temperatures, shorter.The higher the quantity of material mixed, the shorter the potlife. To achieve alonger potlife at high temperatures the mixed material may be divided into smallerunits or both components may be cooled before mixing.

System Application a) Apply the mixed resin Sikadur-330 to the prepared substrate using a trowel or

brush in a quantity of approximately 0.7 to 1.2 kg/m2, depending on roughnessof substrate.

b) Place the SikaWrap Hex-430G (VP) Fabric onto the resin coating in therequired direction. Carefully work the fabric into this resin with the plastic SikaLaminating Roller until the resin is squeezed out between the rovings.

c) Application of more than one fabric layer (max. 3).Apply more resin, consumption approximately 0.5 kg/m2.This must be done within 60 minute (at 20

oC) after the application of the

previous layer.If this is not possible, a waiting time of at least 12 hours must be observedbefore the next layer is applied, Then repeat step B.

d) As a covering layer an additional resin layer of approximately 0.5 kg/m2broadcast with quartz sand can be added, which will serve as a bonding coatfor following cementitious coatings.

Important Information In fiber direction , overlapping of the fabric must be at least 100 mm.When placing several fabric webs side by side overlapping is not necessary.

At low temperatures and/or high relative humidity, the surface may becomesticky .Before a further coat or adhesive or a further layer of fabric is applied (laterthan 12 hours after the previous one) the thickness must first be removed asfollows :Wash down with sponge saturated with water and rinse with plenty of water.Mixed leftover of Sikadur-330 may only left to harden in metal containers andin quantities of max 1 kg.Prevent exposure of the reinforcement to direct sunlight

Ambient temperature during application must be at least 3o

C above dewpoint.Max. admissible service temperature +50

oC

Cleaning Clean all tools immediately with Colma Cleaner.Cured Sikadur-330 can only be mechanically removed.

Safety InstructionsSafety precautions Before starting work, cover hands and unprotected skin with barrier cream. Wear

protective clothing (gloves, glasses). In contact with eyes or mucous membranesrinse thoroughly with warm, clean water and seek medical help.

Ecology In liquid form Sikadur-330 contaminates water. Do not dispose of into water or soilbut according to local regulations.
